* Optimise calculating device_list changes in `/sync`. (#11974)Erik Johnston2022-02-151-0/+1
For users with large accounts it is inefficient to calculate the set of users they share a room with (and takes a lot of space in the cache). Instead we can look at users whose devices have changed since the last sync and check if they share a room with the syncing user.
